The aim of current study was to investigate the effects of swimming endurance training on induction of liver hepatic metallothionein (MT) in pregnant rats exposed to cadmium poisoning. Materials and Methods: Thirty-two pregnant rats (200 ± 20 g) were divided into four groups (control, swimming training, cadmium, and swimming training+ cadmium). Cadmium chloride was given orally (400 mg/kg in drinking water) from the first day of pregnancy until delivery. Training protocol was included 60 minutes swimming for 5 days a week during pregnancy. Liver tissues were removed two days after delivery. Liver MT levels and apoptotic index were determined by ELISA method and nonradioactive in situ end labeling method using TUNEL immunocytochemical technique, respectively. The ANOVA and post hoc LSD tests were used to analyze the data of study at p ≤ 0.05. Results: Swimming endurance training significantly decreased cadmium-induced apoptosis (p =0.005), but had no effect on liver MT levels. Conclusion: Although, swimming endurance training had no effect on liver MT levels, but decreased cadmium-induced apoptosis presumably via other mechanism than induction of liver MT. Thus, it was somewhat effective to contrast with cadmiuminduced cell death.Journal of Practical Studies of Biosciences in Sport (JPSBS)University of Birjand2383-01821

مازندران، بابلسرauthorNiloofarKarimiکارشناس ارشد گروه فیزیولوژی ورزشی/ دانشگاه مازندران/ بابلسرauthortextarticle2013perBackground and aim: Various studies indicated increases in systemic inflammation after the intensive strength training, but the effects of the oral Ginger supplement on pro-inflammatory cytokines and acute phase proteins in immediate and 24 hours following strength exercise are not well known. The aim of this study was to investigate the effect of short-term Ginger supplement on markers related to systemic inflammation (interferon gamma and serum Amyloid A [SAA]) as markers of inflammatory and interlokin-2 [IL-2] as an index anti-inflammatory), in the immediate and 24 hr of the Oxford strength exercise in trained men. Materials and Methods: Twenty subjects in a longitudinal design were divided randomly into two groups; the Oxford strength exercise group (experimental) with and without Ginger supplementation, and or the Oxford strength exercise group (placebo) with and without placebo (Starch). Both groups performed the Oxford strength exercise protocol before and after supplementation and or/ placebo period with similar conditions. The subjects of the experimental group orally received 3 capsules (each capsule contained 1000 mg) of Ginger rhizome powder per week. Blood samples were collected at before, immediate and 24 hr after the Oxford strength exercise. Results: Oxford strength exercise in both the experimental and placebo groups significantly increased in the interferon gamma, SSA and IL-2 in immediate and 24 hr after strength exercise, as compared to baseline (resting) levels. However, Ginger supplementation caused attenuates Oxford exercise–induced inflammation. Conclusion: Progressive resistance exercise induced systemic inflammation 24 hr after training and Ginger supplementation was a alternative method for alleviate the effects of exercise-induced inflammation.Journal of Practical Studies of Biosciences in Sport (JPSBS)University of Birjand2383-01821

Physical activity can be considered as an important one. The aim of this study was to examine the effects of acute interval aerobic running and endurance weight training on appetite in overweight men. Materials and Methods: In a plan of one group with repeated measures, 12 overweight men (25>BMI>30) voluntarily participated in this study. Participants divided randomly into 3 equal groups including interval aerobic training, endurance weight training, and control groups. Training protocols carried out in 3 weeks with one reating week in order to cleaning of plasma. Interval aerobic training consisted 3 sets, 10 minutes exercises with a 5 minutes interval rest at intensity of 13th Borg scale; and endurance weight training included 8 movements and 20 repetitions at 40 percent of one repetition maximum (1RM). Moreover, the level of appetite was assessed by Visual Analog Scale. Results: The desire to eat was significantly reduced 9 hours after exercise than pre-test in both training groups (p=0.01). The t-test results also showed no significant difference between two type of exercises (p=0.80). Although, the fullness feeling was increased 9 hours after the exercise in both training groups, however, this change was significant only in the endurance weights training group (p=0.001). These values did not significantly change in the control group. Conclusion: In general, according to the present results, the endurance weight training can have a significant effect on desire to eat and also fullness felling 9 hours after exercise than interval aerobic running. The latter had only significant reduction on desire to eat 9 hours after exercise. Therefore, the endurance weight training can be considerd as a good exercise for reducing of appetite level and it can be benefit for overweight men.Journal of Practical Studies of Biosciences in Sport (JPSBS)University of Birjand2383-01821

Moreover, the complication of these problems can be improved through corrective exercise programs. The aim of this study was to identify the effect of a 6 weeks corrective exercise program on improvement flat foot and static balance. Materials and Methods: This is a semiexperimental research. Samples were consisting of 50 boy students (10-12 years old) with flexible flat foot, they divided into 2 groups: experimental group (35 people) and control group (15 people). Samples were selected according to the Navy- drop test (P: 76%-95%). To measure static balance the Biodex balance system timer was used. Postural stability in the anterior-posterior, internalexternal and overall index balance was achieved. For statistical analysis of data, Kolmogorov– Smirnov test for normal distribution of data and assumptions of the Wilcoxon signed ranks, Man Whitney algorithm and paired t-test with the level of 0.05 was used. Results: The results indicated a significant difference (p=0.001) between pre-test and post-test of the experimental group in flat foot improvement; and there was a significant difference (p=0.003) between post-test values of them. Moreover, balance index of experimental group between pre-test and post-test for the anteriorposterior side (p=0.03), and for overall index (p=0.005), but not in internal-external side (p=0.08), were improved. On the other hand, there were significant differences between experimental and control groups in lateral (p=0.04), anterior-posterior (p=0.005), and total (p=0.009) balance. Conclusion: According to this study, to improve the flat foot deformity and static balance, the corrective exercise program is strongly recommended for the 10-12 years old boy students.Journal of Practical Studies of Biosciences in Sport (JPSBS)University of Birjand2383-01821

In this study, it is established the persian version of CTT and evaluated its psychometrics features for determination of anaerobic threshold in healthy young females. Materials and Methods: Three groups of healthy female students (with low, mid, and high aerobic capacity, n=19) were selected by stratified purposeful sampling. Giving informed consent, they took part in 2 sessions of exhausting graded exercise test (EGXT) which were apart by 1 week. CTT and gas analysis were administered respectively in first and second sessions of EGXT. Ventilatory estimations of CTT were evaluated by results of EGXT. Using SPSS software, data were analyzed using by one-way ANOVA. Results: VO2max of 3 groups were significantly different (F(2, 54)≥32.44 and P≤0.01). Nevertheless, in anaerobic threshold, mean (±SD) of heart rate (HR), Borg scale, and CTT were approximately the same and respectively equaled 177(±10) beat/min, 15(±2) degree and 5(±1) numbers. In anaerobic phase, they were remained the same and respectively equaled 193(±7) beat/min, 18(±1) degree, and 3(±1) numbers. Conclusion: The results showed that CTT can be considered as good as heart rate test and sometimes can be better than Borg scale in determining anaerobic threshold and anaerobic zone. There was a negative linear correlation between CTT and intensity of training. For healthy young females, a counting of 5 indicates working in anaerobic threshold and a counting of 3 means working in anaerobic zone. The use of CTT for determination of anaerobic threshold was confirmed by our findings.Journal of Practical Studies of Biosciences in Sport (JPSBS)University of Birjand2383-01821
